| Abstract: | Mercury(I) chloride reacts with gallium(III) chloride in benzene/1, 2‐dichlorobenzene solution to give the binuclear compound Hg2(GaCl4)2 ( 1 ). Reduction of mercury(I) chloride with mercury in gallium(III) chloride‐benzene mixture leads to the trinuclear compound Hg3(GaCl4)2 ( 2 ). The crystal structures of 1 and 2 were determined by single‐crystal X‐ray diffraction {Hg2(GaCl4)2: triclinic, P1¯, a = 645.21(3), b = 654.44(3), c = 927.17(7) pm, α = 83.526(2)°, β = 74.915(2)°, γ = 61.863(3)°; Hg3(GaCl4)2: monoclinic, P21/c, a = 715.79(1), b = 1501.59(4), c = 1421.43(4) pm, β = 98.9798(9)°}. |
